10d. Trenton Drive Sewer Main Project
A
B
B
B
B
B
The
Trenton
Drive
sewer
main
project
is
funded
through
the
wastewater
capital
funds
in
the
original
capital
improvement
program
budget.
The
design
costs
was
120
thousand
dollars
compared
to
the
proposed
cost
of
170
9066
dollars,
and
the
original
construction
estimate
was
1
million
dollar
plus
hundred-thousand-dollar
contingency
in
the
original
capital
improvement
budget.
C
B
If
you're
familiar
with
this
neighborhood,
the
street
elevation
is
actually
higher
than
the
back
of
the
homes
and
it
goes
downhill
from
there
and
in
those
days
60
years
ago.
I
can
any
anticipate
speculate
that
the
that
would
be
the
easiest
way
for
the
developer,
to
put
it
right
behind
a
home
and
run
it
down
and
prior
to
this
heavy
eucalyptus
growth.
B
And,
of
course,
one
consideration
we
have
to
take
now
is
by
moving
the
sewer
main
to
the
street,
assumed
the
new
sewer
main
would
have
to
be
at
a
much
deeper
elevation
in
order
for
the
sewer
laterals
to
be
rerouted
from
the
back
to
connect
the
new
sewer.
So
that
is
one
of
the
consider
concern
that
we
have
I.
C
B
The
proximities
35
homes,
along
that
35
Laros,
would
have
to
be
really
locate
it
and
we
will
have
to
run
very
long
Laros
from
the
top
from
the
back
of
the
home
all
the
way
down
to
San
Bruno
in
order
to
meet
the
zoo
main
of
the
new
main
on
san
bruno
avenue.
Ok
and
of
course,
that
is
still
a
possibility
but
gloss.
Why
you're
the
profession
which
do
not
think
that
it's
say
a
good
option.
E
B
Directional
boring
between
homes
to
run
a
lateral
pipe
to
the
back
of
the
house
and
connect
make
the
connection
at
the
back.
So
there
would
be
no
interruption
during
the
service,
except
the
point
that
you
need
to
connect
the
two
pipe
in
the
meantime,
while
they're
constructing
this
lateral
to
the
back,
the
existing
level
was
still
discharged,
the
very
main
behind
the
homes.
So
that
is
what
they
propose.
Of
course,
this
directional
boring
of
the
dual
arrow
would
be
between
the
homes
and
not
underneath
the
homes,
and
that's
also
one
will
allow
conceives
concern,
but.
B
B
Direction
drilling
so
it
would
go
underground.
Of
course,
you
will
require
a
maybe
a
right
of
entry
for
work
from
the
homeowners,
their
consent
and
then
at
the
back
of
the
home,
where
the
new
pipe
they
like.
We
would
have
to
do
a
small
excavation
to
connect
the
existing
lateral
to
this
new
pipe
that
will
come
down
to
the
front
of
the
house.
So
there
would
be
a
small
excavation,
but
the
installation
for
the
length
of
the
house
will
be
done
by
directional,
boring.
E
It
seems
to
me
it
maybe
I'm
thinking
that
this
too
simplistically,
but
it
would
require
some
pretty
extreme
angles
for
pipes
that
are
laid
in
the
ground
coming
out
of
the
house
at
one
in
one
direction
and
you're
talking
about
boring
straight
back,
making
a
small
connection
and
then
bringing
it
back.
180
degrees
in
the
opposite
direction.
And
that
to
me
seems
like
something
that
would
cause
issues
with
flow.
B
We
definitely
will
look
into
the
potential
problem
with
running
the
sewer
180
degree
to
the
front,
but
it
has
been
done
before
and,
if
done
correctly,
I
believe
the
we
stopped
believe
that
the
the
hydraulic
of
the
flow
of
sewage,
we
not
tend
that
the
problem
can
be
avoided
by
creating
is
a
nice
smooth
turn
from
the
further
connections
like
a
wider
longer
sweep
and
elbow
rather
than
using
a
very
tight
90
degrees
elbow
those.
Those
were
all
eliminate,
reduce
the
friction
loss
through
the
pipelines
so
and.
D
E
So
it
sounds
like
you
guys
have
done
the
research
Yuba
City.
You
have
the
Yuba
City
example
and
I'm
sure.
There's
some
cost
estimates
there
that
that
you're
using
is
your
your
estimate.
It
just
didn't
seem
as
it's.
It
seems
hard
to
believe
that
you
could
do
it
as
for
the
same
price
or
comparable,
comparable,
a
comparable
price,
doing
something
that's
so
drastically
different
and
and
with
as
little
impact
to
to
the
homeowners
as.
B
I
mentioned
earlier,
the
final
alternative
selection
would
be
based
also
based
on
cost
and
we'll
look
into
the
cost
of
leaving
replacing
the
pipe
in
place
behind
the
homes.
But
in
that
scenario,
there's
a
hidden
costs
also
to
remove
these
hundred
feet,
tall
eucalyptus
tree
and
a
number
of
them,
and
also
to
create
an
access
row
over
the
entire
lineman
of
this
that
we
currently
do
not
have
that
hidden
costs
can
upset
the
castori
Rao
these
lateral
to
the
fun
of
the
up
to
the
street
and
and.
D
B
B
F
Okay,
thank
you.
This
is
just
on
a
you
know,
I
myself,
something
I've
thought
of,
and
somebody
else
has
brought
it
up
to,
but
I
know
in
all
of
our
language
we
have
here.
These
projects
are
an
amount
not
to
exceed
X
dollars
and
always
I,
don't
know
if
there's
better
dead
lawyers
can
come
up
with
better
verbiage,
but
these
not
to
exceed
always
gives
me
this
impression
that
that's
where
your
plateau
is
meaning
that
they
can
go
right
up
to
that
and
obviously
there's
a
change
order.
F
F
D
G
The
director
is
is
correct,
though,
on
construction
contracts,
our
intent
in
using
the
not
to
exceed
language
is
to
make
sure
that
the
total
appropriation
amount
or
the
total
amount
being
authorized
by
the
City
Council
is
not
exceeded.
That
includes
both
the
actual
construction
contract
costs,
as
well
as
the
contingency.
F
And
we
talked
about
the
eucalyptus,
trees
and
obviously
the
height
and
the
Challenger
that
could
have
and
I
and
I
would
perceive
that
over
the
period
of
time
we
haven't,
the
city
has
done,
maybe
nominal
vegetation
removal.
What
have
you
is
most
the
king
and
I
mean
we
can't
go
in
and
take
care
of
all
of
that.
What
other
are
there
any
other
issues
or
concerns
that
we're
going
to
have
other
than?
F
C
One
company
came
up
with
something
figured
that
it's
going
to
cost
them
quarter
of
a
million
dollars
to
do
it.
This
company
is
saying
179
thousand
dollars
to
do
it
and
there's
still
a
lot
of
unknowns.
You've
made
it
very
clear
wing
has
made
it
very
clear
that
there
are
some
very
complex
issues
here
that
are
dealing
with
not
only
the
terrain,
the
trees,
but
also
the
residents
yeah
and
the
property,
so
I
think.
C
A
Rico,
seventh
Avenue,
just
a
quick
question:
I
I
did
read
the
agenda
packet.
Assuming
you
move.
The
new
sewer
line
to
in
the
middle
of
the
street
are
their
costs
involved
to
do
something
with
the
part
that's
green
on
the
map
now
are
you're
going
to
plug
it.
Are
you
going
to
cave
it
in
or
is
it
going
to
stay
there
with
no
no
added
cost
to
the
city?
Thank
you.
D
A
Agree
with
the
vice
mayor,
the
bigger
question
for
me
is
a
a
lot
of
these
costs.
I
don't
want
to
minimize
them,
but
are
very
small
compared
to
the
problem
we
have
with
SSOs
and
the
problem
that
we
have
with
with
the
groups
like
the
bay
keepers
and
things
going
down
the
road,
many
millions
of
dollars,
and
we
we
made
a
very
aggressive
effort
as
this
council,
with
some
of
our
rates
recently
to
get
a
lot
of
this
stuff
taken
care
of
and
I
think
this
is
a
good.
